I hope I am not intruding too much, I am a Drymarchon wannabe owner. The posts here on incubation are always of interest to me, as this is my favorite time in herpetoculture- nest box to pipping.
For anyone else interested I have come across several good books worth reading that focus on reptiles and eggs:

Gunther Kohler- Incubation of Reptile Eggs. Krieger Publishing, 2005 ISBN# 1-57524-193-5
This book seems to be more for general audiences but has a very good series of appendices and literature cited.

D. Charles Deeming and Mark W.J.Ferguson, eds. Egg Incubation: it effects on embryonic development in birds and reptiles. Cambridge University Press 1995
ISBN# 0-521-39071-0
Peer reviewed chapters by experts within the various fields. Still palatable. I ordered this from the publisher’s web page, it should still be available.

D.C. Deeming, ed. Reptilian Incubation: environment, evolution and behavior. Nottingham University Press 2004. ISBN# 1-897676-11-5
Same approach as the previous book only with the sole focus on reptile eggs. I consider this a must have book for anyone serious about understanding what goes on inside the shell. Even still nearly all the authors say there is so much left to learn about species other than those routinely studied (snappers, gators, etc). To me, a better read than the 1995 collection.

Brian Keith Mcnab The Physiological Ecology of Vertebrates- A view from energetics.
Cornell University Press 2002. ISBN# 0-8014-3913-2
One of the better animal physiology books I have come across, makes clear real links between physiology and the environment. Reptiles are not ignored in this book.

I hope in a couple of days once I get the thoughts I would like to say straightened out where there can be a good discussion about eggs and incubation techniques.
